Ok, I built my first sump last night and am in need of some egg crate material or other pourous material to hold filtration media in place.
Where do you buy it and what is it used for? I know I have seen it before, but I am thinking it was in association with lighting or ceiling covers. The hardware store had no idea.
Any help appreciated.
TIA,
